But linear is awesome too for.. um.. linear stuff. Yeah. Like altering large sets of data at the same time, skewing data, etc.

I had to take both. I don't remember discrete much because the dude sitting next to me was jacking off the whole time during class every fucking class and moaning. Every. Fucking. Class. All class. Ugh!

There is plenty of cross-over in both. It really depends on the flavor you are looking for, and the flavor Discrete Math offers. Traditionally, Discrete Math is a survey course, with the professor's favorite topics being covered. It can include logic, set theory, number theory, graph theory, combinatorics, discrete probability and statistics, formal languages, recurrence relations, proof by induction, etc.

Linear Algebra is a common class where proof-writing is taught, but this is a class taught in a lot of different ways too. Sometimes it's more computational (computing determinants, characteristic polynomials, row reductions, etc.), and other times it's more proof-based and abstract (think vector spaces, etc.).

If you get into eigenvalues and eigenvectors in Linear Algebra, that crosses over with Discrete and Diff Eqs. Diagonalizing a matrix is done to solve systems of recurrence relations, differential equations, and you can use matrices to solve systems of congruences.

There is a branch of mathematics called Matroid Theory which blends well with graph theory, linear algebra, and abstract algebra.

Neither will hurt, both will help. Take both if you have room. As a general rule of thumb, if you're going the graphics route, go for Linear. Otherwise, I'd lean Discrete. Your professors and school's resources will be of more help in making these determinations.

I am currently taking both, and as others have said I would recommend both courses as they can compliment other areas of study and each other. If you end up doing linear programming, or are ever dealing with a large system of many unknowns, linear algebra is going to give you the tools to understand how those types of problems can be solved. When you are designing your algorithm, your knowledge from discrete math is going to help you write as optimal of a solution as possible (among other things). If you have the opportunity to take both, definitely go for it.

This should have been posted on the student campus forum. I took discreet but didn't take linear. meh

For what it's worth, I took both subjects and I'm glad I did. Discrete Maths is probably more immediately useful to you, the topics you cover will come up in other CS classes. Linear Algebra is widely used in graphics, and it's a fundamental topic for higher mathematics if you plan on studying any further in that direction.

I took both. Both were good. I would say discrete math though. You should fanangle taking both.

Discrete for general computer science and linear algebra for many applications. Computer graphics is all

Linear algebra, so is data processing, or any simulation with multiple unknowns. It is definitely worth your

time to take the extra class; for such a small amount of time(relatively), the benefits are gargantuan.

Did someone say math?

When I was a boy on the farms of Missouri we had to do our arithmetic with sheep testicles strung on cord as an abacus.

So fuck you.

I didn't take either. I'm doing fine.

I took discrete. They are both useful. I'm surprised no one has mentioned logic in relation to discrete mathematics, which would be useful in logic statements and conditions. Those things that we pretend don't take computing time.

I have to take both. I'm in linear now. It's child's play compared to my differential equations class. I hear discrete is as hard as any higher level math, where linear you can probably sleep through and get an A.

I had to take both, and i took them very recently. Id say discrete because its talked about a lot more often in my other programming classes such as my data structures class. Recursion is a big thing, at least it is in my object-oriented classes. But I must agree, Linear was more enjoyable.

So ultimately its up to you, or just take both!
